CH|LDS CHAIR.

SPECIFICATION formingpart of Letters Patent No. 278,826, dated June 5, 1883.

Application filed July 25, 1882. (No model.)

' To all whom it may concern Be it known that I, LOUIS SCHMETZER, a sub ject of the King of Bavaria, residing at the city of Rothenburg-on-the Tauber, in the Kingdom of Bavaria, German Empire, have invented certain new and useful Improvements in Childrens Chairs, of which the following is a speciiication.

This invention relates to a nursery chair IO which is adjustable into a high, a low, or a walking chair.

The invention consists in certain peculiarities of construction hereinafter described and claimed.

I 5 111 the accompanying drawings, Figure 1 represents a vertical central section of my improved childs chair, the dotted lines showing the position of the same as a walkingchair. Fig. 2 is a top view of the upholstered ring and zo frame used in connection with the walkingchair. Fig. 3 is a vertical longitudinal section of the U-shaped rail and the seat-frame of the chair; and Fig. 4 is a bottom view of the seatframe, showing the method of attaching the vessel or chamber-pot.

Similar letters of reference indicate corresponding parts.

Referring to the drawings a a represent the supporting-legs of my improved child s chair, 0 which legs may be provided at the lower edge with rollers b, and whichare fulcrumed to cast iron frames (1 in the customary manner in chairs of this class. The fulcrumed legs a a are locked into upright position by locking brace-pieces j, which are hinged to the upper ends, a, of the hind legs, and at the other end braced against recessed checks or seats (6"- of the upper ends, a, of the other legs. If the hinged brace-pieces f are released from the front legs and swung into nearly vertical posit-ion on their hinged connection with the hind legs, the legs a. turn on their fulcrums c 0 until they assume the position shown in dotted lines in Fig. 1, in which position they are retained by the inwardly- 5 projecting rims or flanges d of the cast-iron frames (1. In this position of the legs the lower part of the chair may be used as a walkingchair, for which purpose the casters 9 are applied to the lower ends of the chairlegs a. a.

The casters are applied in such a manner to the legs a aand at such an angle thereto that they are lifted sufficiently above the ground when i the chair is resting on the rollers I), while they are thrown into operation when the legs are spread apart, as shown in Fig. 1. In the latter case the rollers b are raised sufficiently above the floor to be thrown out of play.

The cast-iron body-frames (l d of the chair proper are connected at their upper ends by a U-shaped metallic rail, 71, which is shown in Figs. 2 and 3, to which the seat-frame Z of the seat a is detachably applied. For this purpose the U shaped rail 71 is provided at the rear ends with upwardly-bent hooks 71, into which therear part of the seat-frame Z is placed,while the front end of the seat-frame Z is locked by a hook, l to a spring actuated latch, 71?, of the rail h to the frame. To the rail h is furthermore attached, by means of leather or other straps, m, an upholstered ring, m, which is open at the rear part and provided with a buckled strap, m lVhen the seat is removed from the supporting-frame of the chair and the legs a a are secured in locked position the child can be strapped in the ring at, whereby the 75 chair can be used as a walking-chair to enable children to learn to walk with safety. The usual opening in the seat-frame Z is closed by a lid, a, which is attached directly to the under side of the upholstered seat n. The lid a serves thus not only for closing the opening, but also for holding the seat securely in position on the seat-frame. Each cast-iron frame (Z is provided with an inclined forward-extending rail, 3, which is cast integral with the frame or otherwise securely attached thereto. These rails are provided at their inner surface with teeth, into the intermediate recesses of which the pins a of lever 0 project, said levers being pivoted to the supporting-brackets t of the 0 foot-board z. The lower edges of the brackets t have the same inclination as the rails s, and may be raised or lowered along the rails and locked to the teeth by means of a handle which is arranged at one side of the foot-board t. The 5 lovers 1: are forced by springs w in upward direction and into the recesses of the teeth, so that always a reliable interlocking of the pins :20 with the teeth of the rails stakes place. By these means a vertical and horizontal change of position of the foot-board is secured without exerting while in use a too great pressure upon the pins to of the lever r.

By adjusting the foot-board higher or lower it may be adapted to the different lengths of legs of children of different age, the foot-board being made wide enough to form a support whether it is adjusted higher or lower on the inclined rails s.

The childs chair offers a number of advantages. It can be used in the same manner as a common chair, and as awalking-chair by removing the seat and spreading the legs, so as to run on the supplementary casters.

The construction ofthe upholstered seat and the arrangement of the sheet-metal vessel facilitates the use of the chair as a closet, while the adjustable foot-board admits the use of the chair for children of smaller or larger size.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l.-The combination of a body-frame, sup.- porting-legs therefor, a horizontal U-shaped rail connected to said frame, a removable seat supported by said rail, and. means for attach ing said seat to said rail, substantially as described.

2. The combination, in a nursery-chair, of a body-frame, a horizontal U-shaped rail connected thereto, provided with upwardly-bent hooks at its rear and with a latch at its front end, and a removable seat-frame provided with a fastening-hook at its front end, the back of said seat-frame being constructed as described, whereby it is adapted to fit said upwardly-bent hooks of the U-shaped rail, substantially as described.

3. The combination of a body-frame and a horizontal U -shaped rail connected thereto,

provided with a strap and with means for retaining a removable seat,whereby the structure. may be readily converted from a walking to a sitting chair, substantially as described.

4. The combination of a body-frame, legs hinged to said frame, means for locking said legs in upright and in inclined positions, and a U shaped rail connected to said body-frame, provided with a strap and means for retaining a removable seat, whereby the structure is inter-convertible into a high or low, walking, or sitting chair, substantially as described.

5. The combination of a body-frame, provi ded with downwardly-inchned ibrwardly-extended rails provided with a series of notches on their inner sides, and an adjustable footrest, constructed as described, whereby it is adapted to. slide on said rails, and a link, one end of which is pivoted to said foot-rest and the other end provided with a stud adapted to enter the notches in said rails for holding the foot-rest in any desired position thereon, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LOUIS SGHMETZER.
